#### You are given a singly linked list and an integer ‘K’. You are supposed to make ‘K’ th node from the end of a linked list as the starting node of the linked list.

##### Note :
``````Given ‘K’ will always be valid.
``````
##### Input format :
``````The first line of the input contains the elements of the singly linked list separated by a single space and terminated by -1. Hence, -1 would never be a list element.

The second line contains a single integer ‘K’.
``````
##### Output format :
``````Print updated list elements separated by space.
``````
##### Node :
``````You do not need to print anything; it has already been taken care of.
``````
##### Constraints :
``````1 <= N  <= 5*10^5
1 <= K <= N
-10^9 <= data <= 10^9 and data != -1

Time Limit : 1 sec

##### Sample Input 1:
``````7 11 13 17 19 23 29 -1

``````
##### Sample Output 1:
``````19 7 11 13 17 23 29 -1
``````
##### Explanation For Sample Input 1:
``````Removing the third node from the end of the linked list, i.e. 19 and make the head node of the linked list.
